Their rampage put schools on alert for "enemies lists" made by troubled students, but the enemies on their list had graduated from Columbine a year earlier. Contrary to early reports, Harris and Klebold weren't on antidepressant medication and didn't target jocks, blacks or Christians, police now say, citing the killers' journals and witness accounts. That story about a student being shot in the head after she said she believed in God? Never happened, the FBI says now.

A decade after Harris and Klebold made Columbine a synonym for rage, new information — including several books that analyze the tragedy through diaries, e-mails, appointment books, videotape, police affidavits and interviews with witnesses, friends and survivors — indicate that much of what the public has been told about the shootings is wrong.
